	Has anyone tried to milk a SCSI drive for all
it's speed?  I would like to get about 400 Kbytes/sec.
Does anyone have any suggestions?  How low of level do 
I have to write my code?
	Does anyone know about using async FileManager calls?  How
much CPU time is lost when the calls are async?  What is the
optimal buffer size?
	We are using it to interface to a 56000 board
that we built to do real time sound out put from disk.
